Hi! After the RS BOE 14 Days, my family (me, wife and 12 yo son) would like to visit Austria, which is not included in the tour. I have 5 nights/6 days for that between the tour and our flight to home. I originally thought about 3 nights in Vienna, 1 night in Hallstatt and 1 night in Salzburg before heading home out of Frankfurt since we have an evening flight.
After sightseeing in Vienna, we'd like to rent a car in Vienna to visit and see the beauty of Salzkammergut including Hallstatt and the hills and stay there for 1 night. On the next day, we'd return the car in Salzburg and stay there for one night. But since my friends in Frankfurt want us to visit them for at least a day, we have to change the plan.
If we have to stay for only 1 night in either Hallstatt or Salzburg, where should we stay overnight to see both cities? Or should we stick to the original plan and not spend a night in Frankfurt? Or would it even be better to stay in Hallstatt or Salzburg for 2 nights instead of splitting each night?
Any advice would be appreciated.
